Shapeshifting, all forms of life.
Pretty much a mixed bag of usefulness.

Oh, if that's too common a superpower, then mine would be meat generation. Just make meat appear out of thin air. Free the world from hunger. Then when they have begun to completely rely on me as a source of food, take it away and ration my abilities and claim myself as the new world leader!

I like both these. Shapeshifting is golden. And while meat generation is completely unorthodox and not that cool of a power... I like your motives

Ability to level up and gain experience from everyday things. That way, once I ding level 100 after making a PBJ, I can shit talk some huge bouncer dude that will constantly miss his punches, and die from me pinching him.

Energy manipulation- all forms of energy.
Cold? Increase the kinetic energy around you.
Power outage so you can't play WoW? Send electromagnetic energy through the wires to start up your comp + router.

On the flipside- you can kill someone without leaving a trace or rob a bank with ease.

I, personally, have given much thought to this one. My power would he to heal. Heal a hurt, heal a disease, heal an epedemic. I also would not like any power that differentiates me too much from the normal human. Healing, for example, is hard to 'balance' as a power, as too much, and you can even heal old age, so you become immortal, the worst of curses. Too little, and, well, you can figure that out.

Over-all, healing would be my first choice if I was to only choose one.
